“The examining magistrate in charge of the case? Pleased to meet you, M. le juge. This is a terrible business. How’s Mrs. Renauld? Is she bearing up fairly well? It must have been an awful shock to her.”

“Terrible, terrible,” said M. Hautet. “Permit me to introduce M. Bex—our commissary of police, M. Giraud of the Sûreté. This gentleman is M. Hercule Poirot. M. Renauld sent for him, but he arrived too late to do anything to avert the tragedy. A friend of M. Poirot’s, Captain Hastings.”

Stonor looked at Poirot with some interest.

“Sent for you, did he?”

“You did not know, then, that M. Renauld contemplated calling in a detective?” interposed M. Bex.

“No, I didn’t. But it doesn’t surprise me a bit.”

“Why?”

“Because the old man was rattled! I don’t know what it was all about. He didn’t confide in me. We weren’t on those terms. But rattled he was—and badly!”

“H’m!” said M. Hautet. “But you have no notion of the cause?”

“That’s what I said, sir.”
